Overcast days black
Sunny days black
Trolling for walleye, those fish are feeding up..
Picture being under water looking up at bright sky
Even on gloomy days up is brighter
Dark colours will give more of a silhouette..
Where flashy gets lost in any sort of chop, and bright colours don’t give as much contrast
You can never go wrong with dark dipsys or spoons out on Erie
Get on YouTube and search trolling for walleye Lake Erie lots of videos
Let’s be real though the way the walleye population is right now you can throw a weight and a treble on a squished pop can and catch them so go with whatever you have confidence in or is on sale haha
